Causes of Observed Long-Periodic Variations of the Polarization at Polar Regions of Jupiter
Data of 23-years of Jupiter polarimetric observations (1981- 2004) have been reprocessed using new improved technique. The data from other observers have been added to the analysis (1971-74). Anticorrelation between asymmetry of polarization and insolation has been found. The mechanism of influence of seasons changing (through temperature variations) on north-south asymmetry of polarization formation has been proposed. Also a possibility of existence of influence of solar cosmic rays flux on polarization value is noted.
